phase in the eukaryotic cell cycle when the cell is not
actually dividing. Chromosome - CORRECT
ANSWER//gene-carrying structure found in the nucleus
of a eukaryotic cell and most visible during mitosis and
meiosis Cytokinesis - CORRECT ANSWER//any of a family
of plant hormones that promote cell division, retard
aging in flowers and fruits, and may counter the effects
of auxins in regulating plant growth and development
Somatic cell - CORRECT ANSWER//any cell in a
multicellular organism except a sperm or egg ell or a cell
that develops into a sperm or egg; a body cell Haploid -
CORRECT ANSWER//containing a single set of
chromosomes; referring to an n cell Diploid - CORRECT
ANSWER//containing two sets of chromosomes in each
cell, on set inherited from each parent; referring to a 2n
cell Phenotype - CORRECT ANSWER//the expressed
traits of an organism Genotype - CORRECT
ANSWER//the genetic makeup of an organism Dominant
- CORRECT ANSWER//in a heterozygote, the allele that
determines the phenotype with respect to a particular
gene Recessive - CORRECT ANSWER//in a heterozygote,
the allele that has no noticeable effect on the
phenotype What is the monomer of the DNA polymer? -
CORRECT ANSWER//nucleic acids What does DNA stand
for? - CORRECT ANSWER//Deoxyribonucleic Acid DNA vs
,RNA - CORRECT ANSWER//DNA and RNA are both
nucleic acids with some common features and some
differences. Within a cell, DNA directs the production of
RNA, which in turn directs the production of proteins
Know the base-pairing rules for DNA - CORRECT
ANSWER//A = T, and G = C Transcription - CORRECT
ANSWER//the synthesis of RNA on a DNA template
Translation - CORRECT ANSWER//the synthesis of a
polypeptide using the genetic information encoded in an
mRNA molecule Gene - CORRECT ANSWER//a unit of
inheritance in DNA (or RNA in some viruses) consisting
of a specific nucleotide sequence that programs the
amino acid sequence of a polypeptide Bengin - CORRECT
ANSWER//an abnormal mass of cells that remains at its
original site in the body Metastasis - CORRECT
ANSWER//the spread of cancer cells beyond their
original site Allopatric vs sympatric speciation - CORRECT
ANSWER//Allopatric Speciation: occurs in populations
that are separated geographically; in either case,
reproductive isolation prevents interbreeding, even
though populations in sympatry could freely mate.
Evidence for sympatric speciation is rare Sympatric
Speciation: occurs in situations in which a geographic
barrier doesn't isolate the populations undergoing
speciation. The two or more species arising from
sympatric speciation overlap in their geographic ranges
Are there transitional fossils? - CORRECT ANSWER//no
Mutation - CORRECT ANSWER//a change in the
nucleotide sequence of DNA; a major source of genetic
diversity Macroevolution - CORRECT
ANSWER//evolutionary change above the species level,
, including the origin of evolutionary novelty and new
taxonomic groups and the impact of mass extinctions on
the diversity of life and its subsequent recovery
Speciation - CORRECT ANSWER//an evolutionary process
in which one species splits into two or more species
Biogeography - CORRECT ANSWER//the study of the
geographic distribution of species, provides much
evidence for the evolution of life on earth Ingroup -
CORRECT ANSWER//a species or group of species whose
evolutionary relationships we seek to determine
Taxonomy - CORRECT ANSWER//the branch of biology
concerned with identifying, naming, and classifying
species Plate Tectonics - CORRECT ANSWER//theory
explaining the structure of the earth's crust and many
associated phenomena as resulting from the interaction
of rigid lithospheric plates that move slowly over the
underlying mantle Fitness - CORRECT ANSWER//the
genetic contribution of an individual to the next
generation's gene pool relative to the average for the
population, usually measured by the number of
offspring or close kin that survive to reproductive age
Comparative Anatomy - CORRECT ANSWER//scientific
study of anatomical, morphological, and functional
changes among vertebrates Bioinformatics - CORRECT
ANSWER//the use of computers, software, and
mathematical models to analyze biological information
Population - CORRECT ANSWER//a group of interacting
individuals belonging to one species and living in the
same geographic area at the same time Fossil - CORRECT
ANSWER//a fossil is the evidence of or preserved
remains of an organism that once lived Be able to trace
